You can request all of your service records, including your DD214 on the VA website.
I just ordered two more certified copies of my DD224 last year. Took about 3 weeks. (No cost of course.)

You said you're 80. Vietnam vet? If so, apply immediately for Agent Orange exposure. Agent Orange will bump you to 60% at a minimum. Even if you weren't in Nam, exposure to fire pits still qualifies.
-> Important, apply before Trump takes office. Hes stated he intends to stop vets from claiming.
Also have your family doctor send a complete list of all you medications over to your VA doctor. You can get all your drugs through the VA at minimal cost (less than Part D policy.)
If you’re in priority groups 2 — 8.
tier 1 meds are $5
tier 2 meds are $8
tier 3 meds are $11
(Thrse prices are for a 30 day supply, for a 90 day supply multiply by 3)
(Priority group 1 is no copay, = 50% disability rating.)
If you have a service-connected rating of 40% or less, and your income falls at or below the national income limits, your meds are free.
The max copay out-of-pocket is $700 per calendar year.
